Vacheron Constantin Fiftysix complete calendar 40 mm Blue Dial Stainless Steel Leather Strap 4000E/000A-B548

Heir to a model from 1956, this steel watch features a precision moon phase that is accurate over 122 years. This poetic complication is finished with day, date, and month displays. The petrol blue that adorns the dial and strap provides this model with unmatched modernity. Its openworked caseback reveals an elevated oscillating weight in 22K gold, inspired by the Maltese cross.
